The hub system can comprise a hub plate assembly and/or a hub casting assembly. In addition, at least one clamp assembly, preferably cylindrical, can be included for circumferential attachment to the outer surface of the frame members to provide for selective removable fastening of various attachments and accessories at positions along the length of the frame members. The hub plate assembly and the hug casting assembly can be connected individually to the frame members, or in combination, to enable selective angular configuration of the frame members to construct a frame construction, such as those commonly utilized in display frame systems.

RELATED APPLICATIONS

This application is a continuation of application Ser. No. 10/601,843filed Jun. 23, 2003, which claims the benefit of U.S. ProvisionalApplication No. 60/390,489 filed Jun. 21, 2002, with each of saidapplications being incorporated by reference herein in their entirety.

FIELD OF THE INVENTION

The present invention is related generally to displays having supportframework and graphical displays for use as exhibits at trade shows andthe like. More particularly, the invention relates to such displays thatare dissassemblable and that utilize tubular components to selectivelyvary the frame configuration.

BACKGROUND OF THE INVENTION

Exhibits for tradeshows and other marketing venues utilize eye catchingand informative graphical portions that are intended to inform andpresent an image to customers or potential customers. A common use willbe at convention or exposition halls where perhaps a single day isallocated for each of setup and removal. To create desiredattention-getting appeal, such displays can be massive in size andcomplexity. Moreover such convention space is usually extraordinarilyexpensive as is labor for set up and take down of the displays. Thus,such displays need to be designed to be easily and quickly erected andtaken down. Such constraints often make these displays quite expensive.Moreover, often new fresh designs are desirable. Thus it is preferablethat the displays are easily reconfigureable allowing at least thestructural framework components to be reused in alternate displayconfigurations.

The above needs have been met to some extent with collapsible frameworksor collapsible trusses, as illustrated with U.S. Pat. No. 6,149,021, andwith box frame designs, as illustrated with U.S. patent application Ser.Nos. 09/953,111 and 09/953,113. While all of these systems have theiradvantages, the collapsible systems cannot support extensive weight andthe exposed truss systems present an industrial look. Large diametertubular framework systems present a very desirable visual alternative.Such systems have been used in trade show type displays but have not hadthe flexibility and reconfigurability desirable in this type of productline. Generally such large diameter tubular displays must be custom madefor a particular design and involve welded connections and very largesections. Currently, such large framework systems are cumbersome and areoften designed with one particular configuration in mind. If the membersare not welded, they are generally joined using limited fixed jointconnections. Predefined and fixed tees, cross bars, elbows, and the likeare provided to join members in a particular configuration. An inabilityto selectively design and setup such steel tubular framework systems isproblematic. It would be highly desirable to have a large diameterdisplay utilizing large diameter tubing that is easily reconfigurableand dissassemblable. It would also be desirable to be able toincorporate such large diameter tubing framework systems with existingtruss or box frame systems.

SUMMARY OF THE INVENTION

The display of the present invention addresses and solves many of thedescribed problems that innately plague conventional displays. Thepresent invention employs various individual components that are easilyinterconnectable to provide the end user with a myriad of frameworkconfiguration options utilizing large diameter tubing. These componentscan be selectively connected so that only those components are used thatprovide the user with the optimal configuration. As such, connectivityoptions are increased with the selective combination of only thosecomponents which are needed to meet the user's needs. In addition, therelatively simplistic design of the components and locking options ofthe present invention improves ease of assembly, disassembly, andreconfiguration.

The framework connection system of the present invention generallycomprises a plurality of frame members, preferably tubular, a pluralityof end flanges, and a hub system. The hub system can comprise a hubplate assembly and/or a hub casting assembly. In addition, at least oneclamp assembly, preferably cylindrical, can be included forcircumferential attachment to the outer surface of the frame members toprovide for selective removable fastening of various attachments andaccessories at positions along the length of the frame members. The hubplate assembly and the hug casting assembly can be connectedindividually to the frame members, or in combination, to enableselective angular configuration of the frame members to construct aframe construction, such as those commonly utilized in display framesystems.

An objective and feature of the present invention is the selective useand re-use of common component, such as hub plate and hub assemblies, toprovide for variable frame connection configurations. Displays rangingfrom the simple to the complex are achieved using the same commonmateable components.

Another objective and feature of the present invention is the ability toselectively and modularly connect metallic tubing members, linear andcurvilinear, to construct simple and complex frame connectionconfigurations.

Yet another objective and feature of the present invention is a displayconstructed of a tubular framework having clean and substantiallyuninterrupted visual lines, thus avoiding the conventionalimplementation of cumbersome, bulky, and unappealing hub designs. Thepresent invention provides for substantial circumferential continuity orvisual consistency between the frame member and the connected hubassembly.

Still another objective and feature of embodiments of the presentinvention is a display constructed of strong and durable steel tubularframe members to allow for increased stability and strength while stillpermitting selective modular configuration.

Another objective and feature of embodiment of the present invention isthat the various securing members, such as the set screws, provideengagement with the pins of the mating components to correspondinglybring the components into abuttable or confrontable alignment.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring primarily to FIGS. 1 a-21, the framework connection system 10in accordance with the present invention generally comprises a pluralityof frame members 12, a plurality of end flanges 14, a hub plate assembly16, and a hub assembly 18. Various embodiments of the system 10components, means of connectivity, and configuration options aredescribed and shown in attached Appendix A, which is hereby incorporatedby reference in its entirety. The frame members or segments 12 can betubular steel tubing members, but in alternative embodiments, othermaterials and shapes can be employed. Each of the end flanges 14 areinsertably attachable to at least one end of the frame member 12 suchthat the flange 14 is fixed within at least a portion of the tubingmember 12. The flanges 14 can be fixed to the end portion of the framemember 12 with a weldment bond to facilitate connectivity with othersystem 10 components. Other methods and techniques of attachmentunderstood to one skilled in the art are also envisioned.

Referring to FIGS. 1 a-3, and 21, the frame members 12 of one embodimentcan be constructed of cylindrical steel tubing having a central boretherethrough, and include an end portion 21 and end apertures orrecesses 22 providing communication into the central bore. Wiremanagement openings can further be included along the outer surface ofthe members 12 communicating into the central bore to provide wiring andcabling options throughout the framework. The longitudinal length of theframe members 12 define an axis a₁. The members 12 can be of varyinglengths, depending on the needs of the user. Other embodiments can beconstructed of plastics other suitable materials, and can be constructedof square or rectangular tubing, or other shapes typically used to formdisplay frame constructions. In one of the tubular embodiments, themembers 12 can have an approximate outer diameter of 2½ to 4 inches.This outer diameter is preferably consistent along the entire length ofthe tubing, with the length being variable depending on theconfiguration needs of the manufacturer or end user. The tubing wallthickness is preferably in the range of 0.025 to 0.250 inches, but otherdimensions are also envisioned for use with the present invention. Themembers 12 can be straight or linear, as shown in FIG. 2, or arcuate orcurvilinear, as shown in FIG. 3.

The inner diameter for the tubing bore is some size smaller than theouter diameter, for receiving the end flanges 14, with the end flanges14 defining an axis a₂. The end flanges 14 include a body portion 23 anda face portion 27. The face portion 27 is generally cylindrical to matchthe shape of the end portion 21 of the frame members 12 such that theface 27 of the flange 14 substantially lines up with the end of theframe member 12, or is measurably inset, aligning axis a₁ and a₂. Theflanges 14 can further include a central aperture or recess 24, a bodyaperture or recess 25, and a plurality of indexing or alignmentapertures or recesses 26. Additionally, a plurality of indexing oralignment pins 28 selectively securable within the indexing apertures 26can be provided. At least one connector pin 30, and at least oneconnector fastener 32 can be included as well. The connector pin 30 caninclude at least one securement groove 31 proximate at least one end ofthe pin 30. The connector pins referred to herein can be a one piece pin30, or two distinct but joinable pins 42, 44, wherein one pin, i.e., pin42, comprises male threading, and a second pin, i.e., pin 44, comprisesfemale threading to facilitate connectivity. The longitudinal length ofeach pin 30, 42, 44 defines an axis a₄. Various components may requirepin 30, others may require the connected combination of pins 42, 44, andyet others may only require the threadable insertion of pin 42.Regardless, reference herein to any of the referenced pins 30, 42, 44 ismerely demonstrative as any one of the pins can provide the requisiteconnectivity described. Alternative embodiments of the pins 30, 42, 44can take on various shapes, such as hexagonal or other non-cylindricalforms, along at least a portion of the longitudinal length. As such, theflats or edges of the non-cylindrical pin 30 are mateably inserted intothe flange 14 central aperture 24 having a substantially similar shapesuch that rotation of the confronting tubing members 12 along the commonaxis a₁ is limited as shown in FIG. 1 e.

Referring to FIGS. 1 d-1 e, and 4-5, the central aperture 24 traversesat least a portion of the face 27 of the flange 14 some distance inwardthrough the body 23. The body aperture 25 traverses into the body 23transverse or radial to the central aperture 24 such that the apertures24, 25 are in fluid communication with each other. The body aperture 25can further include a lip proximate the point of communication with thecentral aperture 24 to provide a stop for an inserted connector pin 30.When secured within the end portion 21 of the frame member 12, the bodyaperture 25 of the flange 14 is substantially aligned with the endaperture 22 of the frame member 12 such that a fastener, i.e., the atleast one connector fastener 32, is insertable through both apertures22, 25, radially in relation to axis a₁ and a₂, to fasten the connectorpin 30 in place at the securement groove 31. The central aperture 24 andthe body aperture 24 can be threaded for receipt of various fastenersand/or pins for component connectivity.

The indexing apertures 26 car also include a threading portion forreceipt of the plurality of indexing pins 28. Preferably, the indexingapertures 26 are located along the face 27 of the flange 14, traverse insome distance through the face 27, and are spaced at predeterminedintervals following the diametrical face 27 of the flange 14 to providefor various lockable engagement options. The receivable indexing pins 28can include a threaded portion to engage corresponding threading in theindexing apertures 26. The indexing pins 28 can provide for neededstability when insertably aligned within those components having indexreceiving apertures. The primary stability function of the indexing pins28 is to limit rotation of the member 12 in relation to interlockedcomponents—i.e., another axially connected frame member 12 with flange14, or a connected hub assembly 18 as shown in FIGS. 1 d-1 e, and 21.Rotational movement about the longitudinal axis a₁ of the member 12 isrestricted by the interlocked indexing pins 28.

A limited portion of the connector pin 30 can be inserted into thecentral aperture 24, aligning axis a₂ and a₄, such that one of thegrooves 31 is alignable with at least one of the end apertures 22 of theframe member 12. The connector fastener 32 is shaped and sized to beremovably threaded into the end aperture 22 and through the bodyaperture 25 of the flange 14, radially in relation to axis a₂ and a₄, tosecurably engage the groove 31 of the connector pin 30, pulling ordrawing the connector pin and the engaging component (i.e., a hub orframe member) into abuttable securement with the flange 14. The at leastone connector fastener 32 can be a set screw, or other fastening meansknown to one skilled in the art for selectively engaging or locking withsuch a pin 30. Bolts, screws, and a myriad of other fasteners andfastening means are envisioned for use throughout the present inventionwhen component connectivity is required. The various setscrew fastenersof the present invention can be easily adjustably threaded into therespective apertures or recesses utilizing a setscrew wrench, such asthat shown in FIG. 21.

Referring primarily to FIGS. 8-9, the hub plate assembly 16 can includea hub plate 33 having at least one connecting branch 34. The plate 33can further include a plurality of index receiving apertures or recesses36, and a central plate aperture or recess 38. Each of the connectingbranches 34 of the hub plate 33 can include a plurality of branchapertures or recesses 40. The branch apertures 40 can completely passthrough the branch 34, or they can define dimpled depressions in thebranches 34. The hub plate assembly 16 can further include a first plateconnector pin 42 and a second plate connector pin 44, or alternatively,a single unitary-bodied pin. Preferably, the plate connector pins 42, 44are removably connectable to one another through the central aperture38. This connectivity option can be achieved with the use of a threadedportion, wherein one of the pins includes a female threaded portion andthe other pin includes a mail threaded portion, and the connectivity ofthe pins 42, 44 leaves a non-threaded portion of each pin, and axis a₄,extending out transverse from the plane of the plate 33. Other knownconnection methods and techniques are also envisioned.

The hub plate 33 generally has a circular inner portion 35 preferablyintegral with the at least one connecting branch 34 such that the atleast one branch 34 extends out from the inner portion 35 substantiallyalong the same plane. The indexing apertures 36 are preferably spacedaround the central aperture 38 through the circular inner portion 35 andare adapted to receive the indexing pins 28 for selective lockableengagement, as demonstrated in FIG. 1d. Embodiments of the hub plate 33will employ varying branch 34 options, at varying angularconfigurations. For instance, one embodiment will include a singlebranch 34, as shown in FIG. 8. Other embodiments will include theangular branch 34 options shown in FIGS. 13 and 20. As the figures show,specific embodiments include connecting branches 34 extending away fromthe inner portion 35 of the hub plate 33 at ninety degree increments,while other embodiments include one-hundred-twenty degree andone-hundred-thirty-five degree increments. A myriad of angular branch 34configurations in addition to those shown can be employed withoutdeviating from the spirit and scope of the present invention.

Referring to FIGS. 6-7, and 10-13, embodiments of the hub assembly 18are shown. The hub assembly 18 generally comprises a hub 46, and atleast one connector fastener 60. The hub 46 can include a central hubaperture or recess 48, a plurality of index receiving apertures orrecesses 50, at least one fastening aperture or recess 52, a receivingslot 54, at least one hub contour 56, and a hub face portion 58. In oneembodiment, the hub 46 is generally cylindrical in cross-section (forcertain cylindrical tubular frame member 12 systems), defines an axisa₃, and is adapted for connection to the frame member 12 by selectivelysecuring a grooved portion 31 of the connector pins 30, 42 through thecentral hub aperture 48 with the connector fastener 60. Alternatively,the connector pin 42 can include a threaded portion threadablyinsertable into a mateable threaded central hub aperture 48 such thatthe groove portion 31 extends out from the hub face portion 58. Like theconnector fastener 32 for the end flange 14, the connector fastener 60of the hub assembly 18 can be a setscrew or like fastening means. Asdescribed herein, the other grooved portion 31 of the pin 42 is securedby the connector fastener 32 through the end aperture 22 of the framemember 12 and through the aligned body aperture 25 of the flange 14 suchthat it engages and selectively locks the connector pin 42 in placewithin the flange 14. As such, the hub 46 is lockably engaged to the endportion 21 of the frame member 12 at the end flange 14, thus aligningaxis a₁ and a₃, as best demonstrated in FIGS. 1 d-1 e, and 21. Thisconnection results in the receiving slot 54 facing out from the framemember 12.

In one configuration, the index receiving apertures 50 are located on,and pass through, the face portion 58 of the hub 46 for receivablealignment with the indexing pins 28 of the end flanges 14, or othercomponents. The fastening apertures 52 pass through the outercircumferential surface of the hub 46, through the hub 46, and intocommunication with the central aperture 48 and the receiving slot 54.The receiving slot 54 passes through the central axis of the hub 46, atthe portion of the hub 46 distal the face portion 58 and traverses adistance into the hub 46 short of the face portion 58. The slot 54 isgenerally sized and shaped so that it is capable of slidably receivingthe at least one branch 34 of the hub plate 33, as demonstrated in FIGS.10-13. Once received and positioned, at least one of the branchapertures 40 of the respective branch 34 is aligned and in communicationwith the fastening apertures 52 of the hub 46, wherein a connectorfastener 60, such as is demonstrated in FIG. 13, locks the branch 34 inplace. The at least one hub contour 56 is sized and shaped to enableconfronting slidable engagement with the at least a portion of the outercircumferential surface of corresponding tubular frame members 12, asshown in FIG. 1 d-1 e. As best demonstrated in FIGS. 1 d, and 19-21, thecontours 56 of multiple hubs 46 interlocked around the connectingbraches 34 of the intermediate hub plate 33 provide sufficient spacingfor receiving the flange 14 and indexing pins 28 of a respectivetransversely or radially aligned frame member 12.

The present invention 10 can further include corner joint assemblies100, such as a fixed corner assembly 102 and/or a pivot corner assembly104, as shown in FIGS. 14-18. The fixed corner assembly 102 of FIGS.14-15 can include a fixed base portion 106 and a fixed angle portion112. The fixed base portion 106 includes a plurality of base indexingapertures or recesses 108, a concave portion 109, and a central apertureor recess 110. The fixed angle portion 112 includes a corner faceportion 114, a plurality of angle portion indexing apertures or recesses116, and an angle portion central aperture or recess 117. The fixedangle portion 112, in one embodiment, is oriented substantially ninetydegrees from the axis of the fixed base portion 106. Other fixed anglesbetween the angle portion 112 and the base portion 106 are envisioned inalternative embodiments. The base indexing apertures 108 and the angleportion indexing apertures 116 are both adapted to receive the indexingpins 28 of the end flanges 14 to provide selective engagement of thefixed corner 102 to respective frame members 12 to provide angularcorner portions in a design frame construction. Similarly, the centralapertures 110, 117 of the fixed corner assembly 102 are capable ofreceiving connector pins 30, 42 for further securement at one end withinthe central aperture 24 of respective end flanges 14 for attachmentusing the connector fastener 32 and methods described herein. Theconcave portion 109 is sized and shaped to compatibly confront at leasta portion of the outer circumferential surface of a respective framemember 12 upon connection of the end flange 14 to the fixed angleportion 112, as demonstrated in FIG. 15. Indexing pins 28 are also usedas with any component capable of lockable engagement with the flange 14of a frame member 12.

The pivot corner assembly 104 of FIGS. 16-18 can include a pivot baseportion 120, and a pivot arm 132. Locking interval pins 140 can also beincluded. The pivot base portion 120 can include pivot base firstindexing apertures or recesses 122, a pivot base central aperture orrecess 124, a pivot base concave portion 126, a pivot base axial groove128, and pivot base second indexing apertures or recesses 130. The pivotarm 132 includes a pivot aperture or recess 134, a pivot centralaperture or recess 135, a pivoting device 136, and pivot arm indexingapertures or recesses 138. The pivot arm 132 is capable of pivotablemovement around the pivot device 136 for selective angularconfigurations. When a specific angular setting is obtained, the pivotdevice 136, such as a pin, screw, bolt, and the like is lockably securedto temporarily fix the pivot arm 136 at the desired angle. In theembodiment of FIG. 16, the locking interval pins 140 are insertable intoa portion of the pivot arm 136 to further stabilize the pivot arm 36upon setting the arm 136 to the desired angle. These locking intervalpins 140 are generally insertable into groove apertures or recesses 129within the axial groove 128 of the base portion 120, and can providepredefined, but selective, angular configurations for the pivot arm 136of approximately zero degrees, forty-five degrees, and ninety-degreeincrements. Other predefined angular options are also envisioned.Without the interval pins 140, the arm 136 is capable of adjustmentalong a myriad of angular settings. Again, the central apertures 124,135 of the pivot corner assembly 104 are capable of receiving connectorpins 30, 42 for further securement at one end within the centralaperture 24 of respective end flanges 14 for attachment using theconnector fastener 32 and methods described herein. The concave portion126 defines a curved surface allowing the end of the pivot arm 136,distal the pivot central aperture 135, free pivoting movement. Indexingpins 28 are also used as with any component capable of lockableengagement with the flange 14 of a frame member 12.

Referring primarily to FIGS. 19-31, various plates, caps, end plates,and like components can be attached to frame member 12 end portions 21via the versatile and modular end flange 14 design and/or the hub plate33. For instance, FIGS. 19-21 show the implementation of an end fillercap 80 attachable to the hub plate 33 which is thereby secured to theflange 14 of the frame member 12. The end filler cap 80 can include atleast one cap aperture or recess 81, and a plurality of cap indexingapertures or recesses 81 a. The at least one cap aperture 81 can receiveany one of the connecting pins 30, 42 to provide coupleable engagementwith the hub plate central aperture 38 and the central aperture 24 ofthe flange 14. The connecting pin, preferably one of the two joinablepins 42, 44, is then locked in place with the connector fastener 32through the end aperture 22 of the frame member 12. Again, the indexingpins 28 can provide rotational stability. The cap indexing apertures 81a can receive one end of the indexing pins 28 while the other is alignedwith an indexing aperture 26 of the flange 14. End filler caps 80 of thepresent embodiment can increase aesthetic appeal by closing off exposedhub 18 and hub plate 16 components. Further, the end filler caps 80 canincrease stability and strength of frame member 12 junctures by fillingin the voids between the hub 18 and hub plate 16 assemblies. The hubcontours 56 of proximate hub assemblies 18 in a hub juncture, such asthose shown in FIGS. 19-21, are each generally shaped and sized toengage a portion of the circumferential surface of the end filler cap80.

Various end caps 150 a, 150 b can also be employed with the presentinvention to cap off exposed flanges 14 of the members 12. For instance,FIGS. 22-25 show two embodiments of the end caps 150 a, 150 b coupled insuch a manner. FIGS. 22-23 show a large end cap 150 a, the cap 150 aincluding a cap aperture or recess 152 for securably receiving one ofthe connector pins 42, 44 for insertion into the central aperture 24 ofthe flange 14. In a preferred embodiment, a pin 42 having male threadingat one end is threadably secured within the cap aperture 25 such that agrooved end 31 of the pin 42 is insertable within the central aperture24 of the flange 14. As such, fastener 32 engages the groove 31 of theconnector pin 42 through the end aperture 22 of the frame member 12 toselectively lock the cap 150a in place. In addition, indexing pins 28within the indexing apertures 26 of the flange 14 can be inserted intoaligned apertures in the cap 150a to provide rotational stability. FIGS.24-25 show a thin end cap 150 b, wherein the end cap 150b includes thecap aperture 152 for threadably receiving the threaded connector pin 42.Again, a grooved portion 31 of the connector pin 42 is insertable withinthe central aperture 24 of the flange 14 to provide selective lockableengagement with fastener 32 through end aperture 22 of the frame member12. In at least one embodiment, this relatively thin end cap 150 bembodiment does not utilize indexing pins 28. Aesthetic appeal andfunctionality are enhanced with each of the end caps 150 a, 150 b.

To facilitate standing frameworks, it may be necessary to includevarious stands, feet, pods and other supporting members at end portionsof particular frame members 12. FIGS. 26-31 demonstrate embodiments ofthese supporting members adapted for implementation with the presentinvention. In FIGS. 26-27 a base stand 154 including a base standcoupling 156 is shown for use with the present invention. The base stand154 is generally disc shaped and can be of varying sizes depending onthe support needs of the particular framework configuration. Othershapes and proportional configurations are envisioned as well. The basestand coupling 156 is connectably positioned on the base stand 154 forlockable engagement with the hub plate 33 of the hub plate assembly 16or the flange 14 of the frame member 12. When connected to the hub plate33, connector pin 42 can be insertable within the flange 14 centralaperture 24, while the other connector pin 44 is insertable into thebase standing coupling through a centrally traversing coupling aperture158. A side stand fastening aperture 160 transverse to, but incommunication with, the coupling aperture 158 can be included forreceiving the connector fastener 60 to lock the base stand 154 againstthe grooved portion 31 of the inserted pin 44. Indexing pin 28 can beutilized to further secure the base stand 154 to the hub plate assembly16 for increased rotational stability.

The base pod 164 is generally diskshaped and includes a threaded shaft 165 extending out from the pod 164.The base cap 166 can include a plurality of base cap apertures orrecesses 170. In attaching the foot pod 162 to the flange 14 of theframe member 12, the hub plate 33 is positionally aligned intermediatethe flange 14 and the base cap 166 such that the pod fasteners 168 canbe inserted up into the base cap apertures 170, through the indexreceiving apertures 36 of the hub plate 33, and into the indexingapertures 26 of the flange 14, as best shown in FIG. 28. Upon alignment,the fasteners 168 can be tightened to fasten the base cap 166 to the hubplate 33 at the end portion 21 of the frame member 12. The threadedshaft 165 of the base pod 164 can then be threadably inserted andsecured within one of the base cap apertures 170, as shown in FIG. 29.As such, a support stand or pod is provided at the end of the respectiveframe member 12 to increase stability and support for the frameworksystem 10. FIG. 31 shows another view of an embodiment of the foot podsystem 162, with base cap 166, being connected through to the hub plate33 of a two hub assembly 18 system.

An alternate embodiment of the foot pod system 162 is included in FIG.30. This embodiment includes the base pod 154 and corresponding threadedshaft 165. However, connectivity with the frame member 12 can beachieved without the base cap 166 or intermediate hub plate 33. Tofacilitate this connection to the flange 14 of the frame member 14, thethreaded shaft 165 can further include an end ball joint 176, and alongitudinally threadably adjustable elongate nut 172 having anintermediate groove 174. The elongate nut 172 is insertable along withthe threaded shaft 165 into the central aperture 24 of the flange 14,along aligned axis a₁ and a₂, wherein the fastener 32, such as thesetscrew 32, can secure the foot pod 162 in place by engaging theintermediate groove 174 of the elongate nut 172. Longitudinaladjustments of the elongate nut 172 along the length of the threadedshaft 165 provide for selective height adjustments for the pod 162 inrelation to the respective frame member 12. The ball joint 176 is atleast partially shrouded within the base pod 164 to enable angularadjustments of the shaft 165 in relation to the base pod 164.

Referring to FIGS. 32-36, the framework connection system 10 can furtherinclude a clamp assembly 20. In one embodiment, the clamp assembly 20can include a first clamp 62, a second clamp 64, and lock fasteners 68,with each clamp including locking channels 66, attachment apertures 70,inner circumferential surfaces 72, outer circumferential surfaces 76,and an inner attachment lining 74. In those embodiments utilizingcylindrical tubing frame members 12, the clamp assembly 20 issubstantially cylindrical, with the inner surface 72 sized and shapedfor confronting engagement around the outside surface of the framemembers 12. In addition, the outer circumferential surfaces 76 of theclamps 62, 64 can include surface flats 76 a. Any surface of the clamps62, 64 can include the attachment apertures 70, including the flats 76a. Unlike conventional clamping devices, the clamp assembly 20 of thepresent invention permits selective placement and removal of the claimassembly 20 along the length of the frame member 12 without the need toremove all frame attachments or appurtenances. The clamp portions 62, 64can be separated and removed, wherein conventional unitary-bodied clampsrequire users to slide the clamp off an end portion of the frame memberafter removing each shelf, lamp, or other appurtenance that may bepositioned between the clamp and the end of the frame member.

The first clamp 62 and the second clamp 64 are joined at the confrontinglocking channels 66 of the respective clamps 62, 64 for selectiveengagement with a corresponding frame member 12. The locking fasteners68, such as screws, bolts, and like means are inserted into the channels66 to secure the clamps 62, 64 together around the frame member 12.Other locking means known to one skilled in the art can also beemployed.

The inner attachment lining 74 is generally positioned along the innercircumferential surfaces 72 of the clamps 62, 64, and as a result, caninclude two separate linings 74. The lining 72 can serve many purposes,such as minimizing damage to the frame member 12 during the positioning,adjusting, and removing of the clamp assembly 20 from the frame members12, and to facilitate attachment. In one embodiment, the attachmentlining 74 can be constructed of plastics, rubbers, or other likematerials to protect the surfaces of the clamp assembly 20 and theengaged frame member 12 from scratching, and to provide effectiveslidability. In another embodiment, the lining 74 is constructed of amagnetic material or member to facilitate ease-of-attachment andstability during use. In both embodiments, the lining 74 can be attachedto the inner surfaces 72 of the clamps 62, 64 with adhesives or otherknown bonding techniques and means.

Various other embodiments of the clamp assembly 20, with one suchembodiment shown in FIG. 32 a, will include a hinge device 67, whereinthe first clamp 62 includes a first hinge portion 67 a and the secondclamp 64 includes a second hinge portion 67 b. Generally, one of therespective first and second clamp locking channels 66 and lockingfasteners 68 are replaced with the hinge 67 and the corresponding hingeportions 67 a, 67 b. The corresponding hinge portions 67 a, 67 b arepivotably mateable with a member such a hinge pivot pin 69 therethrough.The hinge 67 provides a pivoting joint connecting the clamps 62, 64 forselective rotational adjustment of the clamps 62, 64 in relation to eachother to facilitate placement on and removal of the assembly 20 from theframe members 12. Tab receiving recesses 71 can be included forattaching the inner lining 74, as shown in FIG. 32 a. However, otherhinged embodiments of the clamp assembly 20 will connect a liner,magnetic member, and the like to the inner circumferential surface 72 ofat least one of the clamps 62, 64 using the adhesive or other bondingtechniques and methods described herein.

A myriad of frame system attachments and appurtenances 178 can besecured to the frame members 12 by way of the clamp assembly 20 and theattachment apertures 70, as shown in FIGS. 34-36. For instanceappurtenances 178 such as computer monitor support bars, screenattachment tubing and apparatus, lighting, banner connectors, shelves,literature racks, plasma supports, support brackets, CPU cabinets,keyboard tables, counters, and like components and accessories systemscan be selectively attached to the attachment apertures 70 of the clampassembly 20. Referring to FIG. 34, a collar frame connector assembly 180is shown. The collar assembly 180 generally includes at least one collarbracket 190 secured to the attachment apertures 70, and a linkingassembly 192. The collar assembly 180, and the linking assembly 192 inparticular, are adapted to lockably engage the flange 14 of a framemember 12 to provide an additional connectivity option for the presentinvention.

FIG. 35 shows two clamp assemblies 20 spaced along the length of theframe member 12 to provide support for a display mounting assembly 182,such as those used to support computer displays and plasma screens. Thedisplay mounting assembly 182 can include a frame assembly andconnecting brackets 186, wherein the brackets 186 are secured to theattachment apertures 70 of the clamp assembly 20. FIG. 36 demonstrateshow a clamp assembly 20 can be utilized to secure a counter appurtenance190 to the framework system at selective locations along the length of aframe member 12. The counter or shelf 190 is positioned to rest upon theclamp assembly 20 and secured into at least one of the clamps 62, 64through the attachment apertures.

FIGS. 37-38 show a bracket device 192 which can include a central bodyportion 194, at least one bracket branch 196, bracket indexing apertures198, and a bracket central aperture 200. Connector blocks 202 can alsobe included to provide modular connectivity for other tubing members,such as those tubing segments, members, and devices disclosed and taughtin U.S. patent application Ser. Nos. 09/953,113 and 09/953,111, whichare hereby incorporated by reference in their entirety. Other connectorsor small tubing segments can be joined to the bracket device 92 usingvarious connections, such as clips, snaps, tracks, and like connectionmeans without deviating from the spirit and scope of the presentinvention. The branch 196 can be elongate branches as shown in FIGS.37-38, or they can take the form of clips or other connectors. Inaddition, a plurality of branches 196 can be employed, at various angleswith respect to the central portion 194 and other branches 196. Thecentral body portion 194 is preferably sized and shaped for intermediatepositioning and securement between two frame members 12 and theircorresponding flanges 14 with the bracket branch 196 extending somedistance out transverse or radial to the axis a₁ of the frame members12. As such, the bracket central aperture 200 and the bracket indexingapertures are adapted to intermediately receive the connector pin 30, 42and indexing pins 28, respectively, as demonstrated in FIG. 37. Uponsecurement of the end portions 21 and flanges 14 of the confrontingframe members 12, the bracket device 192 is locked into place.

The system 10 of the present invention can further include variousassemblies and connection components adapted to facilitate compatibleinterconnectivity with other framing systems. For instance, an end plate82 assembly, as in FIGS. 39-40, having a plurality of receivingapertures or recesses 83 can be included to connection to box frameassemblies such as the system described and disclosed in previouslyincorporated U.S. patent application Ser. Nos. 09/953,113 and09/953,111. The receiving apertures 83 can be spaced to matchcorresponding box frame trusses or other frame members on one side, andaligned for lockable connection with indexing pins 28 and/or theconnector pin 42 of the end flanges 14 on the other side. Connectors,such as the connector blocks 202, can be secured to appropriate portionsof at least one side of the end plate 82 to facilitate connection to theother frame members. As shown in FIG. 39, and as described herein, theconnector pin 30, 42 can be threaded at one end for attachment to theend plate assembly 82. Other embodiments may weld the plate 82 to theframe members 12, or implement a myriad of other attachment techniquesand methods. With such a configuration it is possible to join framesystems having very different shapes and structural characteristics,such as the joining of cylindrical tubing framing systems to squaretubing box frame systems. Other possible combinations and end plateshapes are envisioned for joining frame systems having different shapes.

Referring primarily to FIGS. 1 d-1 e, and 21, in use the frameworkconnection system 10 of the present invention provides the end user witha wide variety of angular configuration options using selectivecombinations of one or more of the end flanges 13, the hub plateassemblies 16, and the hub assemblies 18. The following examples aremerely to provide instruction on some of the potential permutationsavailable to the end user, and are not intended to be at all exhaustive.

In one embodiment, the system 10 can be quite simplistic in itsconfiguration by providing for a direct connection of two axiallyaligned frame members 12. With such a configuration, the connector pin30 having two substantially identical ends with grooves 31, is insertedinto the central apertures 24 of the respective flanges 14 along axisa₂, wherein connector fasteners 32 are inserted through the endapertures 22 of the frame members 12 to removably lock the frame members12 abuttably together. The connector fasteners 32 engage the grooves 31of respective end portions of connector pin 30 to achieve engagement inone embodiment. The indexing pins 28 can be included within the indexingapertures 26 of abutting flanges 14 to provide rotational stability. Aplurality of these frame members 12, straight or curvilinear, can beconnected one after the other in series.

In other embodiments, as demonstrated in FIGS. 1 d-1 e, and 21, the hubplate 33 and corresponding connecting branches 34 are connectable to hubassemblies 18 to further increase the angular configuration options ofthe system. Generally speaking, a corresponding hub 46 and hub assembly18 is matched with every connecting branch 34 of the subject hub plate33 such that the hub plate 33, and the inner portion 35 in particular,interpose the hubs 46. The branches 34 are slidably received in thereceiving slots 54 of the hubs 46. In those embodiments wherein thebranches 34 are positioned at ninety-degree intervals, this will resultin a maximum of four angular options along the plane of the plate 33,for each plate 33 integrated into the system 10. For instance, as shownbest in FIG. 1 d, a three-way hub plate assembly 16 can be included,wherein the three hub plate 33 connecting branches 34 are connectable tothree transversely aligned respective hub assemblies 18 via the hubreceiving slots 52. In turn, the hub assemblies 16, at the end oppositethe receiving slots 52, are locked with connector pins 30, 42, and/oraligned with the indexing pins 28, to axially align the hub assemblies16 with the respective flanges 14 of the frame members 12 along axis a₁and a₂. Further, two frame members 12 can be lockably secured to theinner portion 35 of the hub plate 33, transverse to the plane of theplate 33, using the plate connector pins 42, 44. With such aconfiguration, a five member 12 juncture is created. Alternatively, afiller cap 80 can be inserted to fill in the exposed inner portion 35 ofthe plate 33.

Similarly, if a four branch 34 hub plate 33 is employed, it is possibleto create a six member 12 juncture. Even a rather simple one way branch34 hub plate assembly 16 can provide for a three member 12 juncture withthe attachment of the hub 46 to the one branch 34, and the transverseattachment of two additional members 12 at the inner portion 35 of theplate 33. Moreover, clamp assemblies 20, filler caps 80, end plates 82,corner joints 100, base stands 154, foot pods 162 and other componentsand assemblies can substitute for, or be incorporated with, the members12. It should be obvious to one skilled in the art that the removal,addition, and the selective combination of various system componentsleaves the end user with a multitude of angular, functional, andaesthetic configuration options, of which only a few have been describedto merely advance an understanding of the advantages of the presentinvention. Combining the selective modular configuration of system 10 ofthe present invention with other appurtenances 178, screens, andcomponents and systems known to one skilled in the art for use withdisplay frameworks are demonstrated in FIGS. 1 a-1 c.
